Our Leadership Team
Dedication. Expertise. Passion.
Peggy Seymour
President
My name is Peggy Seymour. I am the President of MSE Landscape Professionals. After 30-year careers, me as a Registered Nurse and Mike as a Branch Manager for a large landscape company, we decided to “put our money where our mouth was” and transform the landscape industry. Our experience in the four companies that Mike had worked with was that only one person truly benefitted: the owner. Employees were underpaid, undervalued, and promised a litany of rewards that never materialized. Clients were underserved and promises were broken frequently. It just plain didn’t work for us.
We knew that we could do better. We opened MSE Landscape during the recession of 2007. We believed that we could create a company that put people above profit, put our clients first and always served our community. Mike would be responsible for all operations, and I was (and still am) responsible for sustaining and expanding our culture. We committed to always treat our employees and customers with the respect and gratitude they deserved. Servant leadership would be our brand.
It worked. By 2009, MSE was a 3-million-dollar company, with happy employees and loyal customers. We have since grown to be an 11-million-dollar company with offices throughout Southern California. As President, I am responsible for who we are. I am hands-on in the hiring and onboarding process, branding, employee training and development, community relations and strategic planning. To this day, our customers and employees come first. Our community, including the 22 charities that MSE supports, come next. We continue to grow profitably. It’s working and I am proud of what we have created.
